These earthquakes began on the fifth of February, 1783, and continued
until the latter end of the May following, doing infinite damage, and
exhibiting at Messina, in the parts of Sicily nearest to the continent,
and in the two Calabrias, a variety of phenomena. The part of the
Calabrian provinces most affected by this heavy calamity, lies between
the thirty-eighth and thirty-ninth degrees of latitude, being the
extreme point of the continent; and the greatest force of the
earthquakes was exerted at the foot of the particular mountains of the
Apennines, named Monte Deio, Monte Sacro and Monte Caulone, extending
westward to the Tyrrhene sea. The towns, villages and farm-houses,
nearest to these mountains, whether situated on the hills, or in the
plains, were totally ruined by the first shock, which happened about
noon; and there the destruction of lives was the greatest. The towns
still more remote, were, however, greatly damaged by the subsequent
shocks, particularly those of the seventh, twenty-sixth and
twenty-eighth of February, and that of the first of March. The earth was
in a constant tremor, and its motions were various, being either
vortical, horizontal or oscillatory, that is, by pulsations or beatings,
from the bottom upward. This variety increased the apprehensions of the
unfortunate inhabitants, who momentarily expected that the earth would
open beneath their feet, and swallow them up. The rains had been
continual and violent, often accompanied by lightning and furious gusts
of wind. There were many openings and cracks in the earth; and several
hills had been lowered, while others were quite level. In the plains,
the chasms were so deep, that many roads were rendered impassable. Huge
mountains were severed, and portions of them driven into the valleys,
which were thus filled up. The course of several rivers was changed; and
many springs of water appeared in localities which had before been
perfectly dry.
From the city of Amantea, situated on the coast of the Tyrrhene sea, in
lower Calabria, proceeding along the western coast to Cape Spartivento,
in upper Calabria, and thence along the eastern coast to Cape Alice, a
part of lower Calabria, on the Ionian sea, the towns and villages,
amounting to nearly four hundred, whether on the coast or inland, were
either totally destroyed, or suffered greatly. At Casal Nuovo, the
Princess Gerace, and upward of four thousand of the inhabitants, lost
their lives. At Bagnara, the number of dead amounted to upward of three
thousand; and Radicina and Palmi experienced a similar loss. The total
amount of the mortality occasioned by these earthquakes, in Sicily and
the two Calabrias, was, agreeably to the official returns, thirty-two
thousand, three hundred and sixty-seven; but Sir William Hamilton
thought it still greater, and carries his estimate to forty thousand,
including foreigners. On the first shock of the earthquake, on the fifth
of February, the inhabitants of Scylla escaped from their houses, built
on the rock, and, following the example of their prince, took shelter on
the sea-shore. By this shock the sea had been raised and agitated so
violently, that much damage had been done on the point of the Faro of
Messina; but here it acted with still greater violence, for, during the
night, an immense wave, which was falsely represented to have been
boiling hot, and to have scalded many persons on its rising to a great
hight, flowed furiously three miles inland, and swept off in its return
two thousand, four hundred and seventy-three of the inhabitants, with
the prince at their head, who were either at that time on the strand, or
in boats near the shore.
The shocks felt since the commencement of these formidable earthquakes,
amounted to several hundreds; and among the most violent may be reckoned
the one which happened on the twenty-eighth of March. It affected most
of the higher part of upper Calabria, and the inferior part of lower
Calabria, being equally tremendous with the first. Indeed, these shocks
were the only ones sensibly felt in Naples. With relation to the former,
two singular phenomena are recorded. At the distance of about three
miles from the ruined city of Oppido, in upper Calabria, was a hill,
having a sandy and clayey soil, nearly four hundred feet in hight, and
nearly nine hundred feet in circumference at its basis. This hill is
said to have been carried to the distance of about four miles from the
spot where it stood, into a plain called _Campo di Bassano_. At the same
time, the hill on which the city of Oppido stood, and which extended
about three miles, divided into two parts: being situated between two
rivers, its ruins filled up the valley, and stopped their course,
forming two large lakes, which augmented daily. The accounts from Sicily
were of a most alarming nature. The greatest part of the fine city of
Messina was destroyed by the shock of the fifth of February, and what
remained was greatly injured by the subsequent shocks. The quay in the
port had sunk considerably, and was in some places more than a foot
beneath the water. That superb building, the palazzata, which gave the
port a more magnificent appearance than any other in Europe could boast,
was entirely thrown down; and the lazaretto greatly damaged. The citadel
suffered little; but the cathedral was destroyed, and the tower at the
point of the entrance of the harbor much damaged. The wave which had
done so much mischief at Scylla, had passed over the point of land at
the Faro, and swept away twenty-four persons. The accounts from Melazzo,
Patti, Terra di Santa Lucia, Castro Reale, and from the island of
Lipari, were very distressing, but the damage done there by the
earthquakes not so considerable as at Messina.
Sir William Hamilton, from the limited boundaries of these earthquakes,
was persuaded that they were caused by some great operation of nature,
of a volcanic kind. To ascertain this, he began his tour by visiting the
parts of the coasts of the two Calabrias which had suffered most from
this severe visitation. He everywhere came to ruined towns and houses,
the inhabitants of which were in sheds, many of them built on such
insalubrious spots, that an epidemic had ensued. These unfortunate
people agreed that every shock they had felt, seemed to come with a
rumbling noise from the westward, beginning usually with the horizontal
motion, and ending with the vortical (or whirling) motion, which last
had ruined most of the buildings. It had also been generally observed,
that, before a shock, the clouds seemed to be fixed and motionless; and
that, after a heavy shower of rain, a shock quickly followed. By the
violence of some of the shocks, many persons had been thrown down; and
several of the peasants described the motion of the earth as so violent,
that the tops of the largest trees almost touched the ground from side
to side. During a shock, the oxen and horses, they said, kept their legs
wide asunder, to prevent being thrown down, and gave evident signs of
being sensible of the approach of each shock. Being thus warned, the
neighing of a horse, the braying of an ass, or the cackling of a goose,
drove them from their temporary huts.
From Monteleone, Sir William descended into the plain, and passed many
towns and villages in a ruined state: the city of Mileto, lying in a
bottom, was totally destroyed, without a house standing. Among the many
examples afforded by these earthquakes, of animals being able to live a
long time without food, was that of two hogs, which had remained buried
under a heap of ruins at Soriano for forty-two days, and were dug out
alive. He had frequent opportunities for observing that the habitations
situated on high grounds, having a soil of a gritty sandstone, somewhat
like granite, but without its consistence, suffered less than those in
the plain, the soil of which is a sandy clay. The latter were
universally leveled with the ground. During the first shock, he was
told, a fountain of water, mixed with sand, had been forced to a
considerable hight: prior to this phenomenon, the river was dry, but it
soon returned and overflowed its banks. The other rivers in the plain
underwent the like vicissitudes; to account for which, Sir William
supposes the first impulsion of the earthquake to have come from the
bottom upward; and that such was the fact, the inhabitants attested. The
surface of the plain having suddenly risen, the rivers, which are not
deep, would naturally disappear; and the plain seeking with violence its
former level, the rivers would necessarily return and overflow, at the
same time that the sudden depression of the boggy grounds would as
naturally force out the water which lay hidden beneath the surface.
It had been stated, in the reports made to the government, that two
tenements, named Macini and Vaticano, had, by the effect of the
earthquake, changed their situation. In this fact Sir William agrees,
and he accounts for it in the following manner. They were situated in a
valley surrounded by high grounds, and the surface of the earth which
had been removed, had probably been long undermined by the little
rivulets which flow from the mountains, and which were in full view on
the bare spot the tenements had deserted. He conjectures besides, that,
the earthquake having opened some depositions of rain-water in the
clayey hills which surrounded the valley, the water, mixing with the
loose soil, and taking its course suddenly through the undermined
surface, had lifted it up, together with the large olive and mulberry
trees, and a thatched cottage, floating the entire piece of ground, with
all its vegetation, about a mile down the valley, where he saw it, with
most of the trees erect. These two tenements occupied a space of ground
about a mile in length, and half a mile in breadth. There were in the
vicinity several deep cracks in the earth, not one of which was then
more than a foot in breadth; but Sir William was credibly assured, that,
during the earthquake, one had opened wide, and had swallowed up an ox
and nearly a hundred goats. In this valley he saw hollows, in the form
of inverted cones, from which water and sand had been ejected violently
at the time of the earthquakes, similar to those which had been pointed
out to him at Rosarno. As well at the latter place, as in every ruined
town he visited, an interesting remark was made to him, namely, that the
male dead were generally found under the ruins, in the attitude of
struggling against the danger; but that the attitude of the females was
usually with the hands clasped over the head, as if giving themselves up
to despair, unless they had children near them: in this case they were
always found clasping them in their arms, or in some attitude which
indicated their anxious care to protect them. How striking an instance
of maternal tenderness!
Sir William traveled four days in the plain, in the midst of
indescribable misery. Such was the force of the first shock, on the
fifth of February, that the inhabitants of the towns were buried in an
instant beneath the ruins of their houses. Of the population of the town
of Polistene, which was badly situated between two rivers, wont to
overflow their banks, twenty-one hundred individuals perished out of six
thousand. It was built near a ravine of great depth; and, by the violent
motion of the earth, two huge portions of the ground on which a
considerable part of the town, consisting of several hundreds of houses,
stood, were detached into the ravine, and nearly across it, to the
distance of about half a mile from their original position. What was
most extraordinary, many of the inhabitants of these houses, who had
taken this singular leap in them, were dug out alive, and several
unhurt. Terra Nuova lost three-fourths of a population of sixteen
hundred inhabitants; and near to this town and to the ravine, many acres
of land covered with trees and corn-fields had been detached and thrown
into the latter, often without having been overturned, insomuch that the
trees and crops were growing as well as if they had been planted there.
Other such pieces of ground were lying in the bottom, in an inclined
situation; and others, again, were quite overturned. Two immense
portions of land, having been detached opposite to each other, filled
the valley, and stopped the course of the river, the waters of which
formed a great lake.
Having walked over the ruins of Oppido, Sir William descended into the
ravine, which he carefully examined. Here he saw the wonderful force of
the earthquake, which had produced exactly the same effects as in the
ravine of Terra Nuova, but on a scale infinitely greater. The enormous
masses of the plain, detached from each side of the ravine, lay in
confused heaps, forming real mountains; and, having stopped the course
of two rivers, great lakes were formed. He occasionally met with a
detached piece of the surface of the plain, many acres in extent, with
the large oaks and olive-trees, having lupines and corn beneath them,
growing as well, and in as good order at the bottom of the ravine, as
their companions from which they had been separated, were in the plain,
at least five hundred feet higher, and at the distance of about
three-quarters of a mile. Entire vineyards, which had taken a similar
journey, were in the same order in the bottom. In another part of the
ravine was a mountain, composed of a clayey soil, which was probably a
portion of the plain, detached by an earthquake at some former period:
it was in hight about two hundred and fifty feet, and about four hundred
feet in diameter at its basis. It was well attested, Sir William
observes, that this mountain traveled down the ravine nearly four miles,
having been put in motion by the first shock. The abundance of rain
which fell at that time; the great weight of the newly detached pieces
of the plain, which were heaped up at its back; the nature of its soil;
and particularly its situation on a declivity: these, in his opinion,
satisfactorily account for this phenomenon. The Prince of Cariati showed
him two girls, one of the age of about sixteen years, who had remained
eleven days without food under the ruins of a house in Oppido; and the
other, about eleven years of age, who had been under the same
circumstances six days, but in a very confined and distressing posture.
Sir William describes the port of Messina, and the town, in their
half-ruined state, when viewed by moonlight, as strikingly picturesque.
On landing, he was assured by several fishermen, that, during the
earthquake of the fifth of February, at night the sand near the sea was
hot, and that in many parts they saw fire issue from the earth. This had
been often repeated to him in the Calabrian plain; and the idea he
entertained was, that the exhalations which issued during the violent
commotions of the earth, were full of electric fire, just as the smoke
of volcanoes is constantly observed to be during violent eruptions; for
he did not, during any part of his tour, perceive an indication of
volcanic matter having issued from the fissures of the earth. He was,
therefore, convinced that the whole damage had been done by exhalations
and vapors only. In this city, where they had so long an experience of
earthquakes, he was told, that all animals and birds are, in a greater
or less degree, more sensible of an approaching shock of an earthquake
than any human being; but that geese, above all, were the soonest and
the most alarmed at the approach of a shock: if in the water, they quit
it immediately, and they can not be driven into it for some time after.
The force of the earthquakes, although very violent at Messina, and at
Reggio, on the opposite side of the strait, was not to be compared to
that which was felt in the plain. In the former city the mortality did
not exceed seven hundred, of a population of thirty thousand. A curious
circumstance happened there also, to prove that animals can sustain life
for a long time without food. Two mules belonging to the Duke of
Belviso, remained under a heap of ruins, the one twenty-two, and the
other twenty-three days: for some days after they refused their food,
but drank plentifully, and finally recovered. There were numberless
instances of dogs remaining many days in the same situation; and a hen,
belonging to the British vice-consul, having been closely shut up
beneath the ruins of his house, was taken out on the twenty-second day,
and recovered, although at first it showed but little signs of life:
like the mules, it did not eat for some days, but drank freely. From
these instances, and from those above related, of the girls at Oppido,
and the hogs at Soriano, as well as from several others of the same
kind, it may be concluded, that long fasting is always attended with
great thirst, and a total loss of appetite.
A circumstance worth recording, and which was observed throughout the
whole coast of the part of the Calabrian provinces which had been most
affected by the earthquakes, was, that a description of small fishes,
named =cicirelli=, resembling what in England are called white-bait, but
larger, and which usually lie at the bottom of the sea, buried in the
sand, were, from the commencement of these earthquakes, and for a
considerable time after, taken near the surface, and in such abundance
as to become the common food of the poorer sort of people; whereas,
before these events, they were rare, and reckoned among the greatest
delicacies. Fishes in general having been taken, wherever the effects of
the shocks had reached, in much greater abundance, and with greater
facility than before, Sir William conjectures, either that the bottom of
the sea may have been heated by the volcanic fire beneath it, or that
the continual tremor of the earth had driven the fishes out of their
strongholds, in the same way as an angler, when he wants a bait, obliges
the worms to come out of a turf on the river-side, by trampling on it
with his feet, which motion never fails of its effect.
The commandant of the citadel of Messina, assured him, that on the fatal
fifth of February, and the three following days, the sea, at the
distance of about a quarter of a mile from that fortress, rose and
boiled in a most extraordinary manner, and with a horrid and alarming
noise, while the water in the other parts of the Faro was perfectly
calm. This appeared to him to point out exhalations or eruptions from
cracks at the bottom of the sea, which were probably made during the
violence of the earthquakes; and to these phenomena he ascribes a
volcanic origin. He thus attempts to explain the nature of the
formidable wave which was represented as boiling hot, and which, as has
been already noticed, was so fatal to the inhabitants of Scylla.
Sir William concludes by remarking, that the local earthquakes here
described, appear to have been caused by the same kind of matter as that
which gave birth to the Æolian or Lipari isles. He conjectures that an
opening may have been made at the bottom of the sea, most probably
between Stromboli and upper Calabria; for from that quarter, it was
agreed by all, the subterraneous noises seemed to proceed. He adds, that
the foundation of a new island, or volcano, may have been laid, although
it may be ages, which to nature are but moments, before it shall be
completed, and appear above the surface of the sea. Nature is ever
active; but her acts are in general carried on so very slowly, as
scarcely to be perceptible to the mortal view, or recorded in the very
short space of what we call history, let it be ever so ancient. It is
probable, also, he observes, that the whole of the destruction he has
described, may have simply proceeded from the exhalations of confined
vapors, generated by the fermentation of such minerals as produce
volcanoes, which would escape where they met with the least resistance,
and would consequently affect the plain in a greater degree than the
high and more solid grounds by which it is surrounded.
Count Francesco Ippolito, in speaking of the last great shock of the
twenty-eighth of March, as it affected the Calabrian territory, is
persuaded that it arose from an internal fire in the bowels of the
earth, for it took place precisely in the mountains which cross the neck
of the peninsula formed by the two rivers, the Lameto and the Corace,
the former of which flows into the gulf of St. Euphemia, and the latter
into the Ionian sea. All the phenomena it displayed, made this evident.
Like the other shocks, it came in a south-west direction: the earth at
first undulated, then shook, and finally rocked to and fro to such a
degree, that it was scarcely possible to stand. It was preceded by a
terrible groan from beneath the ground; and this groan, which was of the
same duration with the shock, terminated with a loud noise, like that of
the explosion of a mine. These thunderings accompanied not only the
shock of that night, and of the succeeding day, but likewise all the
others which were afterward felt; at the same time that the earth was
continually shaken, at first every five minutes, and subsequently each
quarter of an hour. During the night, flames were seen to issue from the
ground in the neighborhood of Reggio, toward the sea, to which the
explosion extended, insomuch that many of the peasants ran away through
fear. These flames issued precisely from a spot where some days before
an extraordinary heat had been perceived. After this great shock there
appeared in the air, in a slanting direction, and toward the cast, a
whitish flame, resembling electric fire: it was seen for the space of
two hours.
Several hills were either divided or laid level; and within the surface
of the earth apertures were made, from which a great quantity of water,
proceeding either from subterraneous concentrations, or from the rivers
adjacent to the ground thus broken up, spouted for several hours. From
one of these openings, in the territory of Borgia, and about a mile from
the sea, there issued a large quantity of salt water, which for several
days imitated the motions of the sea. Warm water likewise issued from
the apertures made in the plains of Maida. In all the sandy parts, where
the explosion took place, there were observed, from distance to
distance, apertures in the form of an inverted cone, emitting water, and
which seemed to prove the escape of a flake of electric fire. Amid the
various phenomena which either preceded or followed this particular
shock, the following are well deserving of notice. The water of a well
at Maida, which was of an excellent quality, was affected, just before
the shock, with so disgusting a sulphurous flavor, that it could not
even be smelled. On the other hand, at Catanzaro, the water of a well,
which before could not be used, on account of its possessing a strong
smell of calcination, became drinkable. For a long time before the earth
shook, the sea was considerably agitated, so as to terrify the
fishermen, at the same time that there was not a breath of wind. On the
side of Italy, the volcanoes had not emitted any eruptions for a
considerable time before; but in the same way as, during the first great
shock, Etna was in flames, so Stromboli emitted fire during this last.
EARTHQUAKES IN PERU, &c.
South America has been at all times very subject to earthquakes; and it
is remarkable, that the city of Lima, the capital of Peru, situated in
about twelve degrees of south latitude, although scarcely ever visited
by tempests, and equally unacquainted with rain as with thunder and
lightning, has been singularly exposed to their fury. They, indeed,
happen so frequently there, that the inhabitants are under continual
apprehensions of being, from their suddenness and violence, buried
beneath the ruins of their houses. Still they have their presages, one
of the principal of which is a rumbling noise in the bowels of the
earth, heard about a minute before the shocks are felt, and seeming to
pervade all the subterraneous adjacent parts. This is followed by the
dismal howlings of the dogs, who seem to give notice of the approaching
danger; while the beasts of burden, in their passage through the
streets, stop suddenly, as it were by a natural instinct, and seek the
attitude which may best secure them from falling. On these portents, the
terrified inhabitants flee from their houses into the streets, forming
large assemblies, in the midst of which cries of children are blended
with the lamentations of the females, whose agonizing prayers to the
saints increase the common fear and confusion. In a word, the entire
city exhibits a dreadful scene of consternation and horror.
Since the establishment of the Spaniards in Peru, the first earthquake
in this capital happened in 1582; but the damage it did was much less
considerable than that of some of those which succeeded. Six years after
Lima was again visited by an earthquake, the results of which were so
dreadful, that it is still solemnly commemorated every year. In 1609, a
third convulsion threw down many houses: and on the twenty-seventh of
November, 1630, so much damage was done by an earthquake, that in
acknowledgment of the city not having been entirely demolished, a
festival is also on that day annually celebrated. On the third of
November, 1654, the most stately edifices in Lima, and a great number of
houses, were destroyed by a similar event; but the inhabitants having
had timely presages, withdrew themselves from their houses, insomuch
that few perished. In 1678, another dreadful concussion took place.
Among the most tremendous earthquakes with which the Peruvian capital
has been visited, may be reckoned that which happened on the
twenty-eighth of October, 1687. The first shock was at four in the
morning, when several of the finest public buildings and houses were
destroyed, with the loss of many lives. This was, however, merely a
prelude to what followed; for, two hours after, a second shock was felt,
with such impetuous concussions, that all was laid in ruins, and every
description of property lost. During this second shock the sea retired
considerably, and then returned in mountainous waves, entirely
overwhelming Callao, the seaport of Lima, distant five miles, as well as
the adjacent country, together with the wretched inhabitants. From that
time six other earthquakes were felt at Lima, prior to that of 1746,
which likewise happened on the twenty-eighth of October, at half past
ten at night. The early concussions were so violent, that in somewhat
more than three minutes, the greater part (if not all) of the buildings
in the city, were destroyed, burying under their ruins such of the
inhabitants as had not made sufficient haste into the streets and
squares, the only places of safety. At length the horrible effects of
the first shock ceased; but the tranquillity was of short duration, the
concussions swiftly succeeding each other. The fort of Callao was
dilapidated; but what this building suffered from the earthquake, was
inconsiderable when compared with the dreadful catastrophe which
followed. The sea, as is usual on such occasions, receding to a
considerable distance, returned in mountainous waves, foaming with the
violence of the agitation, and suddenly buried Callao and the
neighboring country in its flood. This, however, was not entirely
effected by the first swell of the waves; for the sea, retiring still
further, returned with greater impetuosity, and covered not only the
buildings, but also the lofty walls of the fortress: so that what had
even escaped the first inundation, was totally overwhelmed by these
succeeding mountainous waves. Of twenty-three ships and vessels of light
burden, then in the harbor, nineteen were sunk; and the four others,
among which was a frigate, named the San Firmin, were carried by the
force of the waves to a considerable distance up the country. This
terrible inundation extended, as well as the earthquake, to other parts
of the coast, and several towns underwent the fate of Lima. The number
of persons who perished in that capital, within two days after the
earthquake commenced, on an estimate of the bodies found, amounted to
thirteen hundred, beside the wounded and maimed, many of whom survived
their tortures but a short time.
The earthquake of Jamaica, in 1692, was one of the most dreadful history
has had to record. In the space of two minutes it destroyed the town of
Port Royal, and sunk the houses in a gulf forty fathoms deep. It was
attended with a hollow, rumbling noise, like that of thunder. In less
than a minute, the greater part of the houses, on one side of the
streets, were, with their inhabitants, sunk beneath the water, while
those on the other side were thrown into heaps, the sandy soil on which
they were built rising like the waves of the sea, and suddenly
overthrowing them on its subsidence. The water of the wells was
discharged with a most vehement agitation; and the sea was equally
turbulent, bursting its mounds, and deluging whatever came in its way.
The fissures in the earth were in some places so great, that one of the
streets appeared of more than twice its original breadth. In many places
the earth opened and closed again; and this agitation continued for a
considerable time. Several hundreds of these openings were to be seen at
the same moment: in some of them the wretched inhabitants were swallowed
up; while in others, the earth suddenly closing, caught them by the
middle, and thus crushed them to death. Other openings, still more
dreadful, swallowed up entire streets; while others, again, spouted up
cataracts of water, drowning those whom the earthquake had spared. The
whole was attended with a most noisome stench. The thunderings of the
distant falling mountains, the sky overcast with a dusky gloom, and the
crash of the falling buildings, gave unspeakable horror to the scene.
This dreadful calamity having ceased, the whole island exhibited a scene
of desolation. Few of the houses which had not been swallowed up were
left standing; and whatever grew on the plantations shared in the
universal ruin. These cultivated spots were now converted into large
pools of water, which when dried up by the sun, left so many plains of
barren sand. The greater part of the rivers had, during the earthquake,
been choked by the falling in of the detached masses of mountains; and
it was not until some time after, that they made themselves new
channels. The mountains seem to have been more particularly exposed to
the force of the first tremendous shock; and it was conjectured that the
principal seat of the concussion was among them. Such of the inhabitants
as were saved, sought shelter on board the ships in the harbor, and
remained there above two months, the shocks continuing during that
interval with more or less violence every day.
